After listening to the mini album multiple times, I concluded that H&A has some great songs and I love this unit.
However, there are two 'problems'.
1. This unit screams T.a.t.u. in many aspects. The repetition of vocal lines, effect on the vocals, use of the guitar etc etc. It's not a bad thing, because I actually liked (old) tatu. it's just kinda strange because they're put on the market very differently.
2. It feels artifficial. I can't see Rika enjoying this type of music in her spare time. It is their job, I know. the good thing is that they take everything serious and don't mock the genre/style so to speak. So props on that aspect.
